A bowler's Powerplay?

From Antony Chettupuzha, India
Everybody knows that the Twenty20 format builds on the bias of what was already a batsman-oriented format in ODIs. Well, I'm going to make perhaps the most ludicrous proposal for what is currently a batsman's game: A bowler's power-play. Before you scorn and pepper me with rotten eggs and tomatoes, just hear me out. First all I'm asking for is four overs. Next, the bowler gets to choose the kind of ball he wishes to use in these four overs that will give him the best chances of taking a wicket. This could be a ball deliberately scuffed up to encourage swing bowling, or a new ball or even an old ball for spinners. Finally the field can be set in any possible manner ignoring traditional restrictions. Perhaps even penalize the loss of a wicket with runs (for example take away 15 runs and the wicket, so that the score changes from 100/0 to 85/1).

Now just imagine the excitement, the bowler has everything in his favour and the batting side can choose to either play out these overs safely or, as is more likely, will be forced to try overcome the odds when everything is stacked against them. And that can only make the game more exciting. It probably makes sense to put this right after the batsman's powerplay, so as to set the stage for some sort of fightback while preserving blazing starts and finishes. To me this would be more exciting than a slogfest where sides score and chase over 200 in twenty overs. If anybody has any suggestions on improving this idea of a bowler's power-play or indeed any ideas about evening the contest between bat and ball while maintaining the same level of excitement, I'd love to hear them.
